There are three zones - but just the first zone can be linked to a thermostat which is in the climote hub. For the other zones it just turns on/off as per the timer. By default the zone 1 has the thermostat enabled but it can also be disabled at install. From the manual in the link it looks like you can disable the thermostat post install too in "Installer Settings" menu "Commission Device" option.
